<p><span style="font-size: medium">　　zz有一副神奇的三角板，三角板有两种形状：宽的(Wide)和窄的(Narrow)。三角板都是等腰三角形，宽的三角板底边为高的两倍，窄的三角板底边和高相等。<br />
zz要把n个三角板依次放在桌面上。桌面可以抽象为一根数轴，zz把第i个三角板的底边置于数轴上(y坐标为0)，它的顶点坐标为(xi,yi)，那么，根据三角板的形状，就可以得到另外两个点的坐标了。<br />
每放完一个三角板，zz就会数一遍，目前看得到几个三角板的顶点，如果顶点在其他三角板内(包括边界)，zz是看不见的。并且，当摆放第i个三角板时，如果(xi,yi)已经位于某三角板内，zz认为，这个三角板是放不下的，他便不会放入该三角板。<br />
然而zz的三角板实在太多了，你能帮帮他吗？<br />
